For definitions of indicated parameters please refer to Imaging Processing section of Materials and Methods. Unit for D^* value is × 10^-3 mm²/s. Unit for T_max is second. AUC_w = whole area under the curve, AUC₆₀ = the initial 60-second area under the curve, DCE-MRI = dynamic contrast-enhanced MR imaging, E_max = the maximum amplitude of enhancement, HNSCC = head and neck squamous cell carcinoma, IVIM = intravoxel incoherent motion, T_max = the time at which E_max occurs
